Purpose

The purpose of this document is to generate plots demonstrating the LCI parameter history, and estimate the 2022 LCI budget all for the purpose of updating the Statewide LCI QAPP.

Parameter History

plot of parameter history

It’s important to note that we are collecting Iron Magnesium and Manganese in all waters (class A and B) even though there’s only wqs for water supply use. This is because we started the 5 year random probabilistic sampling before we added dissolved metals. Once that 5 year period is up, we will not be able to summarize dissolved metals statewide so the total values are a temporary proxy. We should remove iron, magnesium, and manganese after this 5 year cycle is up.

Lab Costs - TOTAL

The following is a budget of lab costs for processing the 2022 samples. PLEASE NOTE: there are 6 sites in the probability based sampling list that are tentatively being sampled by CSLAP this year. We are still intending to sample them for LCI because CSLAP’s parameter list is not the same.

Travel Costs

Totals

It’s worth noting that estimated costs are less than we budgeted. This is in part because we are sampling far fewer events than in 2021 (181 events in 2021 compared to the planned 102 events in 2022). Also, we aren’t paying for the NLA lab costs.
